Consider yourself warned. Aurora police will be out tonight looking for curfew violators, and both youth under 18 and their parents may be slapped with a $25 fine.

Aurora’s curfew ordinance says anyone under the age of 18 cannot “loiter on or about any street, alley, sidewalk, parking lot, park, outdoor recreation or common area, or playground” during restricted hours unless they are accompanied by a parent or guardian who is 21 or older.

The restricted hours are from 11 p.m. to 5 a.m. Sunday through Thursday and from midnight to 5 a.m. on Fridays and Saturdays. (Denver’s curfew hours are the same). The fine is $25 and doesn’t require a court appearance, but if the fine isn’t paid a warrant will be issued.

Tonight’s citywide curfew operation is the second one Aurora police have conducted this summer. Last year, officers issued 115 summonses for curfew violations, according to Sgt. Cassidee Carlson. Of those, 80 were tied to criminal activity such as weapons offenses and drug possession.
